INVERSE PROBLEMS IN SCIENCE AND ENGINEERING

Inverse Problems in Science and Engineering provides an international forum for the discussion of conceptual ideas and methods for the practical solution of applied inverse problems. The Journal aims to address the needs of practising engineers, mathematicians and researchers and to serve as a focal point for the quick communication of ideas. Papers should provide non-trivial examples of practical applications. Multidisciplinary applied papers are particularly welcome. Topics include:Shape design: determination of shape, size and location of domains (shape identification or optimization in acoustics, aerodynamics, electromagnets, etc; detection of voids and cracks).Material properties: determination of physical properties of media.Boundary values/initial values: identification of the proper boundary conditions and/or initial conditions (tomographic problems involving X-rays, ultrasonics, optics, thermal sources etc; determination of thermal, stress/strain, electromagnetic, fluid flow etc. boundary conditions on inaccessible boundaries; determination of initial chemical composition, etc.).Forces and sources: determination of the unknown external forces or inputs acting on a domain (structural dynamic modification and reconstruction) and internal concentrated and distributed sources/sinks (sources of heat, noise, electromagnetic radiation, etc.).Governing equations: inference of analytic forms of partial and/or integral equations governing the variation of measured field quantities.

科学与工程中的逆问题为讨论应用逆问题的概念思想和实际解决方法提供了一个国际论坛。该杂志旨在解决执业工程师、数学家和研究人员的需求，并作为快速交流思想的焦点。论文应提供实际应用的重要实例。多学科应用论文尤其受欢迎。主题包括：形状设计：确定域的形状、大小和位置（声学、空气动力学、电磁铁等中的形状识别或优化；空隙和裂纹的检测）。材料性能：介质物理性能的测定。边界值/初始值：确定适当的边界条件和/或初始条件（涉及X射线、超声波、光学、热源等的层析问题；确定热、应力/应变、电磁、流体流动等不可接近边界的边界条件；确定初始化学成分位置等）。力和源：作用于某一领域（结构动力修改和重建）和内部集中和分布源/汇（热源、噪声、电磁辐射等）的未知外力或输入的测定。控制方程：控制测量场量变化的偏微分方程和/或积分方程解析形式的推导。
